Title: The Toulmin Method
1The Toulmin Method
2Essay One Topic Proposal
Part One Describe your topic. What element(s) of
the food system will you be examining? Remember
that your essay, once finished, must suggest a
solution think in terms of a topic that will
allow you to suggest what you want your imagined
audience to do. Part Two Thinking about what
you have read about the Toulmin method, plan the
argument you will make in your essay. Provide
the following Claim The conclusion of the
argument(s) you make in your essay in other
words, the idea that will become your thesis
statement. Backing Give a summary of the
evidence that you will provide. Rebuttal
Exceptions or counterarguments to your claim.
Note--this is not entitled to be the outline of
or plan for your essay rather, it is a
brainstorming exercise designed to help you think
critically about the arguments you will make the
and the approach you will take.
3The Toulmin Method
- Stephen Toulmin, originally a British
logician, is now a professor at USC. He became
frustrated with the inability of formal logic to
explain everyday arguments, which prompted him to
develop his own model of practical reasoning.
4The first triad of his model consists of three
basic elements the claim, ground, and warrant.
5A claim is the point an arguer is trying to
make. The claim is the assertion an arguer wants
us to accept.
- The claim answers the question, So what is your
point? - Example You should eat less fast food because
it is very unhealthy. - Example Slaughter houses are very cruel, so we
should support legislation to make them more
humane.
6There are three basic types of claim
- Fact Claims that focus on empirically verifiable
phenomena - Judgment/value Claims that involve opinions,
attitudes, and subjective evaluations - Policy Claims that advocate courses of action
that should be undertaken.
7- The claim is the point an arguer is trying to
makethe assertion an arguer wants us to accept. - Policy claims advocate courses of action that
should be undertaken. - A policy claim, therefore, is something the
thesis statement of an argumentative essay or
research paper must contain.
8Identify the types of claim fact,
judgment/value, or policy.
- You should eat less fast food because it is very
unhealthy. - Obesity is unattractive.
- Obesity is unhealthy.
- Slaughter houses cause animals to suffer, so we
should support legislation to make them more
humane.
9Identify the types of claim fact,
judgment/value, or policy.
- Claim You should eat less fast food. Policy.
- Claim Obesity is unattractive. Judgment/value.
- ClaimObesity is unhealthy. Fact.
- Claim We should support legislation to make
them more humane. Policy.
10The term ground refers to the proof or evidence
an arguer offers.
- The grounds answer the questions, What is your
proof? or Why?
11Grounds can consist of statistics, quotations,
reports, findings, physical evidence, or various
forms of reasoning.
- Example Fast food consumption has risen 500
percent since 1970 and today pervades nearly
every segment of society, including some public
school cafeterias. At the same time, obesity
among children has tripled.
12Grounds can be based on
- Evidence Facts, statistics, reports, or physical
proof - Source Credibility Authorities, experts,
celebrity endorsers, political pundits, friends,
or parents - Analysis and Reasoning Logical deductive and
inductive reasoning may be offered as proof.
13Not all grounds are equal
- Some information offered as factual may not be
true - Celebrity endorsers, political pundits, family,
and friends often arent as reliable as
researchers and scientists - Induction and deduction can be weak or flawed.
14Satirist Stephen Colbert coined the term
truthiness.
- Truthiness is a quality characterizing a
truth that a person claims to know intuitively
from the gut or because it feels right
without regard to evidence, logic, intellectual
examination, or facts.
15What is the claim (assertion) in each statement?
What are the grounds (ideas offered as proof)?
Look for implications as well as statements.
- Betty is gaining weight I bet she went off her
diet." - That hamburger is probably loaded with calories.
16The warrant is the inferential leap that
connects the claim with the grounds.
- The warrant is typically implicit (unstated)
and requires the reader or listener to recognize
the underlying reasoning that makes sense of the
claim in light of the grounds.
17The warrant performs a linking function by
establishing a mental connection between the
grounds and the claim
- Example Claim Betty is gaining weight I bet
she went off her diet. Warrant sign reasoning
weight gain is a typical sign of eating too much.
- Example Claim That hamburger is probably
loaded with calories. Warrant generalization
most hamburgers are highly caloric.
18Common Warrants
- Argument based on Generalization
- Argument based on Analogy
- Argument via Sign/Clue
- Causal Argument
- Argument from Authority
- Argument from Principle
19Argument based on Generalization
- A very common form of reasoning that assumes
that what is true of a well-chosen sample is
likely to hold for a larger group or population,
or that certain things consistent with the sample
can be inferred of the group/population.
20Argument based on Analogy
- Extrapolating from one situation or event based
on the nature and outcome of a similar situation
or event. Has links to case-based and
precedent-based reasoning used in legal
discourse. What is important here is the extent
to which relevant similarities can be established
between two or more contexts. Are there
sufficient, typical, accurate, relevant
similarities?
21Argument via Sign/Clue
- This is the notion that certain types of
evidence are symptomatic of some wider principle
or outcome. For example, smoke is often
considered a sign for fire. Some people think
high SAT scores are a sign a person is smart and
will do well in college.
22Causal Argument
- This is arguing that a given occurrence or
event is the result of, or is effected by, factor
X. Causal reasoning is the most complex of the
different forms of warrant. The big dangers with
it follow - Mixing up correlation with causation
- Falling into the post hoc, ergo propter hoc
trap. Closely related to confusing correlation
and causation, this involves inferring after the
fact, therefore because of the fact.
23Argument from Authority
- This involves using an authority figure or
text. Important questions follow - Does person X or text X constitute a genuinely
authoritative source on the issue in question? - What political, ideological, or economic
interests does the authority have? - Is this the sort of issue in which a significant
number of authorities are likely to agree on?
24Argument from Principle
- This involves locating a principle that is
widely regarded as right and showing that a
situation exists in which this principle
applies. Questions to ask follow - Is the principle widely accepted, and in what
groups? - Are there commonly agreed on exceptions? Are
there rival principles that lead to a different
claim? - Does it accurately apply to the situation in
question? - Is the principle applied consistently?
- Are the practical consequences of following the
principle sufficiently desirable? - Is the principle based on traditional, religious,
cultural, or other bases that may negate legal
rights or other widely-accepted principles?
25Warrants can be based on
- Ethos Source credibility, authority
- Logos Reason-giving, induction, deduction
- Pathos Emotional or motivational appeals
- Shared values Free speech, fairness, etc.
- Note these categories aren't mutually exclusive
there is considerable overlap among the three.
26Identify how ethos, pathos, and logos can be used
for the following
- You should eat less fast food because it is very
unhealthy. - Obesity is unattractive.
- Obesity is unhealthy.
- Slaughter houses cause animals to suffer, so we
should support legislation to make them more
humane.
27Identify how ethos, pathos, and logos can be used
for the following
- You should eat less fast food because it is very
unhealthy. Ethos and Logos Source credibility
and authority can be used by drawing on credible
experts, and scientific evidence can be supplied.
28Identify how ethos, pathos, and logos can be used
for the following
- Obesity is unattractive. This is a value
judgment, so it cannot be proven as a fact
some cultures, for example, appreciate what
typical Americans would call obesity. In an
argument, you would be most likely to draw on
pathos--emotional or motivational appeals.
29Identify how ethos, pathos, and logos can be used
for the following
- Slaughter houses cause animals to suffer, so we
should support legislation to make them more
humane. Ethos and Logos The opinions of
authorities (Temple Grandin, for example) can be
supplied, and evidence can be produced to
document cruelty pathos would be used in the
documentation of suffering.
30The second triad of the Toulmin model involves
three additional elements
- Backing
- The qualifier
- The rebuttal
31- Backing provides additional justification for the
warrant backing usually consists of evidence to
support the type of reasoning employed by the
warrant it tells us why grounds support claims. - The qualifier states the degree of force or
probability to be attached to the claim the
qualifier states how sure the arguer is about his
or her claim. - The rebuttal acknowledges exceptions or
limitations to the argument the rebuttal admits
to those circumstances or situations where the
argument would not hold.
32The qualifier states the degree of force or
probability to be attached to the claim evaluate
the qualifiers below which is most forceful?
- Betty is gaining weight I think she may have
gone off her diet. - Betty is gaining weight she has obviously gone
off her diet.
33What are some rebuttals to these claims?
- Betty is gaining weight I bet she went off her
diet. - That hamburger is probably loaded with
calories. - Slaughter houses are very cruel, so we should
support legislation to make them more humane.
34Betty is gaining weight I bet she went off her
diet.
- Betty may still be on her diet, but she may have
quit exercising. - Betty may have a medical condition that
contributes to weight gain.
35That hamburger is probably loaded with
calories.
- The hamburger might be a vegetarian substitute.
- The hamburger may be of relatively small size,
made of extra lean meat, and on a lower-calorie,
whole-grain bun.
36Slaughter houses are very cruel, so we should
support legislation to make them more humane.
- Making slaughter houses more humane would
probably drastically raise the cost of meat. - Animals were created for humans to use it
doesnt matter if they suffer. Lots of people
just dont care.(Note these are examples of
possible rebuttals an arguer should anticipate
dealing withthey are not my opinion.)
37Why provide counterarguments?
- Unlike many forms of writing, academic arguments
will often include discussions of possible
objections and counterarguments to the position
being advanced. - Academic arguments typically take place in
disciplinary communities in which a variety of
competing or divergent positions exist.
38Why provide counterarguments?
- When preparing to speak to the community by
writing an argument, writers are aware of the
arguments against which they must build their
claims, and of the counterarguments which are
likely to emerge. - Dealing with counterarguments and objections is
thus a key part of the process of building
arguments, refining them, interpreting and
analyzing them.
39There are several main reasons for introducing
counterarguments and objections.
- By demonstrating that the author is aware of
opposing views and is not trying to sweep them
under the table, it thus is more likely to make
the writer's argument seem fair and honest to
readers, and as a consequence be more persuasive. - Demonstrating that the writer is thinking
carefully about the responses of readers and
anticipating the objections that many readers may
have shows audience awareness. - By contrasting one's position with the arguments
or alternative hypotheses the writer is against,
he or she clarifies the position that is being
argued for.
40Essay One Topic Proposal Part One
- Describe your topic. What element(s) of the food
system will you be examining? - Remember that your essay, once finished, must
suggest a solution think in terms of a topic
that will allow you to suggest what you want your
imagined audience to do. - Your claim, therefore, should be a matter of
policy.
41Part Two Thinking about the Toulmin method, plan
the argument you will make in your essay. Provide
the following
- Claim The conclusion of the argument(s) you will
make in your essay--in other words, the idea that
will become your thesis statement. - Backing Give a summary of the evidence that you
will provide. - Rebuttal Exceptions or counterarguments to your
claim.
42Rememberthere are three types of claim
- Fact Claims that focus on empirically verifiable
phenomena - Judgment/value Claims that involve opinions,
attitudes, and subjective evaluations - Policy Claims that advocate courses of action
that should be undertaken.
43- The thesis statements for this class must be
argumentative (debatable) - They should let your readers know what you want
them to do to solve a problem - Your claim, therefore, should be able to be
categorized as a policy claim, not simply a
factual claim. - Your claim will also be your opinion, but you
should not rely on subjective values.
